Strength in Numbers8" could chain across the entire map. So the bugs are really spread out rather than a swarm clump.

You could make that 4" or 6" to make the swarm more compact and swarm like. 4" would get that.

Skill could be 1d6-1, and Strength gets +1, so back to 1d6.
So 2+ bugs work as normal, a solo bug is 1d6-1

Swarm Stupidity Ok idea but who is going to field 20+ bugs.
Instead of the entire battle field, count the bugs that are in a Strength Swarm and drop the number, to maybe 5.

So you could have a swarm of 5 bugs in 4",
but more than 4" from a nearby swarm of 5 bugs, no penalty.
If the two groups got too close, the Stupidity kicks in.

That could be a tactic the enemy uses against you, if your swarms are too close, push a bug into the gap to make it 6+ bugs in 1 swarm.

ImplantsDo the bugs have an attack besides implants?
Do Implants need a normal attack roll? Does armor defend?
With instant death after an attack roll, this just seems like a normal attack with an angry (two)inch move

Well it would need weapon stats if it were a normal attack.

100% attack success with insta kill seems excessive.

Perhaps this just explains how it gets a normal attack without using a held weapon. It has an internal weapon. Stinger.

I know the strenght in numbers is ludicrus but it has a max of + 1, wihich means each bug can get a 1d6+1 skill or a 1d6, It could chain so ill work on that, The bugs can attack with hands but they can only do 1 damage and that is if you don't get a 1 on a 1d6, The implants attack is 2d6 and you must get 10,11,12 to do it, ill make the new cards
